Even at 75mm (150mm in 35mm terms) you can still see the compression in the lanscape that is not visible at shorter focal lengths. These mountain ranges are miles apart in reality, but appear to be just behind each other in this image. I don't get a chance to photograph something like this too often, so when I do get the chance I take as many different photographs as I can at every folcal length at my disposal. With the 75-300 lens attached I worked the scene but the best image came out at the 75mm setting. There was just enough of the mountain ranges visible to show the compression.
